# Refund

After the user successfully pays, the merchant can initiate a refund through the [Refund Application API](https://docs.payermax.com/api.html?docName=New%20Version&docVer=v1.0&docLang=cn#/paths/aggregate-pay-api-gateway-refund/post) or through the [Merchant Platform](https://docs.payermax.comen/202506-version/mmc/refund-service.html). After PayerMax successfully accepts the request, it will initiate a refund request to the bank or institution, and synchronize the merchant's refund status through the [callback notification](https://docs.payermax.com/en/202606-version/receipt/refund/refund-doc.md#_5-Refund Result Notification). The time limit for the refund to arrive depends on the processing time limit of the bank or institution.

### 1. Conditions For Refund Acceptance

(2) Most payment methods support refunds within 180 days of the transaction. Special payment methods will be noted in the instructions.

### 2. Refund Failed

The refund may fail if the bank or institution cannot process it. If this happens (which is rare), we'll transfer the money back to your Payermax account balance.
